Haas Effect

Technology / Home Audio / Haas Effect: Also known as precedence effect, describes the human psychoacoustic phenomena of correctly identifying the direction of a sound source heard in both ears but arriving at different times. Due to the head's geometry (two ears spaced apart, sometimes separated by a barrier) the direct sound from any source first enters the ear closest to the source, then the ear farthest away. The Haas Effect describes how humans localize a sound source based upon the first arriving sound, if the subsequent arrivals are between 25-35 milliseconds. If the later arrivals are longer than this, then two distinct sounds are heard. The Haas Effect applies even when the second arrival is louder than the first (even by levels as great as 10 db.)
